13 years agoImprove error handling when parsing dirstat parameters
Johan Herland [Fri, 29 Apr 2011 09:36:22 +0000 (11:36 +0200)]
Improve error handling when parsing dirstat parameters

When encountering errors or unknown tokens while parsing parameters to the
--dirstat option, it makes sense to die() with an error message informing
the user of which parameter did not make sense. However, when parsing the
diff.dirstat config variable, we cannot simply die(), but should instead
(after warning the user) ignore the erroneous or unrecognized parameter.
After all, future Git versions might add more dirstat parameters, and
using two different Git versions on the same repo should not cripple the
older Git version just because of a parameter that is only understood by
a more recent Git version.

This patch fixes the issue by refactoring the dirstat parameter parsing
so that parse_dirstat_params() keeps on parsing parameters, even if an
earlier parameter was not recognized. When parsing has finished, it returns
zero if all parameters were successfully parsed, and non-zero if one or
more parameters were not recognized (with appropriate error messages
appended to the 'errmsg' argument).

The parse_dirstat_params() callers then decide (based on the return value
from parse_dirstat_params()) whether to warn and ignore (in case of
diff.dirstat), or to warn and die (in case of --dirstat).

The patch also adds a couple of tests verifying the correct behavior of
--dirstat and diff.dirstat in the face of unknown (possibly future) dirstat
parameters.

13 years agoNew --dirstat=lines mode, doing dirstat analysis based on diffstat
Johan Herland [Fri, 29 Apr 2011 09:36:21 +0000 (11:36 +0200)]
New --dirstat=lines mode, doing dirstat analysis based on diffstat

This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.

The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).

For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.

In linux-2.6.git, running the three different --dirstat modes:

  time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null
vs.
  time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null
vs.
  time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null

yields the following average runtimes on my machine:

 - "changes" (default): ~6.0 s
 - "lines":             ~9.6 s
 - "files":             ~0.1 s

So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.

The patch also includes documentation and tests for the new dirstat mode.

Refactor --dirstat parsing; deprecate --cumulative and --dirstat-by-file

Instead of having multiple interconnected dirstat-related options, teach
the --dirstat option itself to accept all behavior modifiers as parameters.

 - Preserve the current --dirstat=<limit> (where <limit> is an integer
   specifying a cut-off percentage)
 - Add --dirstat=cumulative, replacing --cumulative
 - Add --dirstat=files, replacing --dirstat-by-file
 - Also add --dirstat=changes and --dirstat=noncumulative for specifying the
   current default behavior. These allow the user to reset other --dirstat
   parameters (e.g. 'cumulative' and 'files') occuring earlier on the
   command line.

The deprecated options (--cumulative and --dirstat-by-file) are still
functional, although they have been removed from the documentation.

Allow multiple parameters to be separated by commas, e.g.:
  --dirstat=files,10,cumulative

behavior of the new syntax.

Make --dirstat=0 output directories that contribute < 0.1% of changes

The expected output from --dirstat=0, is to include any directory with
changes, even if those changes contribute a minuscule portion of the total
changes. However, currently, directories that contribute less than 0.1% are
not included, since their 'permille' value is 0, and there is an
'if (permille)' check in gather_dirstat() that causes them to be ignored.

This test is obviously intended to exclude directories that contribute no
changes whatsoever, but in this case, it hits too broadly. The correct
check is against 'this_dir' from which the permille is calculated. Only if
this value is 0 does the directory truly contribute no changes, and should
be skipped from the output.

13 years agodate: avoid "X years, 12 months" in relative dates
Michael J Gruber [Wed, 20 Apr 2011 09:12:11 +0000 (11:12 +0200)]
date: avoid "X years, 12 months" in relative dates

When relative dates are more than about a year ago, we start
writing them as "Y years, M months".  At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:

  Y = days / 365
  M = (days % 365 + 15) / 30

This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").

We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".

Implement this differently with months of size

  onemonth = 365/12

so that

  totalmonths = (long)( (days + onemonth/2)/onemonth )
  years = totalmonths / 12
  months = totalmonths % 12

In order to do this without floats, we write the first formula as

  totalmonths = (days*12*2 + 365) / (365*2)

Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().

But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.

This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.

The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.

13 years agoupload-pack: start pack-objects before async rev-list
Jeff King [Wed, 6 Apr 2011 21:33:33 +0000 (17:33 -0400)]
upload-pack: start pack-objects before async rev-list

In a pthread-enabled version of upload-pack, there's a race condition
that can cause a deadlock on the fflush(NULL) we call from run-command.

What happens is this:

  1. Upload-pack is informed we are doing a shallow clone.

  2. We call start_async() to spawn a thread that will generate rev-list
     results to feed to pack-objects. It gets a file descriptor to a
     pipe which will eventually hook to pack-objects.

  3. The rev-list thread uses fdopen to create a new output stream
     around the fd we gave it, called pack_pipe.

  4. The thread writes results to pack_pipe. Outside of our control,
     libc is doing locking on the stream. We keep writing until the OS
     pipe buffer is full, and then we block in write(), still holding
     the lock.

  5. The main thread now uses start_command to spawn pack-objects.
     Before forking, it calls fflush(NULL) to flush every stdio output
     buffer. It blocks trying to get the lock on pack_pipe.

And we have a deadlock. The thread will block until somebody starts
reading from the pipe. But nobody will read from the pipe until we
finish flushing to the pipe.

To fix this, we swap the start order: we start the
pack-objects reader first, and then the rev-list writer
after. Thus the problematic fflush(NULL) happens before we
even open the new file descriptor (and even if it didn't,
flushing should no longer block, as the reader at the end of
the pipe is now active).

     "foo", but "bar" is dirty in the working tree, it will
     prevent us from applying the stash.

  2. It is redundant. We don't touch the working tree at all
     until we actually call merge-recursive. But it has its
     own (much more accurate) checks to avoid losing working
     tree data, and will abort the merge with a nicer

2010-08-21) handled this by checking for the "Log for stash

ref.

A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:

  git rev-parse --symbolic "$@"

fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.

This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.
